Question

A projectile is fired at time t = 0.0s, from point 0 at the edge of a cliff, with initial velocity components Vox = 80 m/s and and Voy = 800 m/s. The projectile rises, then falls into the sea at point P. The time of flight of the projectile is 200.0 s

In Figure 3.2c, the height H of the cliff is closest to: A)32,130m B)36,000m C)47,490m D)43,650m E)39,810m A projectile is fired at time t = 0.0s, from point 0 at the edge of a cliff, with initial velocity components Vox = 80 m/s and and Voy = 800 m/s.

Explanation / Answer

let the height be hm.so,

just using the equation

s=ut+0.5at^2,

-h=800*200-0.5*9.8*(200)^2

or h=36000

hence the option b is correct
